TOKYO -- Rakuten came out swinging onto Japan's wireless scene with its announcement Tuesday of a price plan with unlimited data at less than half the price of its main rivals.
The e-retailer's 2,980 yen ($27.60) monthly rate would get consumers only about 1 gigabyte of data per month at Japan's three big carriers, or 10 GB at budget mobile companies such as SoftBank Group unit Ymobile.
